Static hybrid amplify and forward (AF) and decode and forward (DF) relaying for cooperative systems

Physical Communication, 2011
Abstract In this paper, we propose a static hybrid amplify and forward (AF) and decode and forward (DF) relaying protocol for cooperative systems. In such a scheme, relays close to the source amplify the received signal whereas the remaining relays transmit only if they decode correctly.

Automatic modulation classification over MIMO amplify and forward (AF)-relay fading channels

Physical Communication, 2021
Abstract Automatic Modulation Classification (AMC) plays an important role in many civilian applications such as spectrum monitoring (SM) and cognitive radio (CR). The majority of the AMC algorithms for MIMO systems are developed for rich scattering environments, which offer a full rank channel matrix.

Evaluation of the PTS PAPR Reduction Technique with the Hammerstein-Wiener Predistortion Model in Amplify-and-Forward (AF), Decode-and-Forward (DF) Relaying Systems over Asymmetric Channels

2021 International Electronics Symposium (IES), 2021
In this paper, we propose and evaluate the joint PAPR reduction with Partial Transmit Sequence (PTS) scheme and predistortion technique at source in cooperative communication systems based Amplify-and-Forward (AF), Decode-and-Forward (DF) protocol over asymmetric channel.
